How much of a battery drain is it to be constantly GPS tracking?
1 comments

<1% per hour. This is achieved by: 1. use consumption patterns to know when to transmit data (eg, if no one is actively tracking, no need to transmit data on radio) [1] 2. using accelerometer and gyroscope data to know when to collect data (eg, if you're not moving, no need to use GPS)

[1] We blogged about how we built out our variable frequency model: https://blog.hypertrack.com/2016/11/28/battery-efficient-rea...

The blog post claims ~5% per hour.
Ah, old post actually, dated Nov 2016. Just wanted to share it for the variable freq approach - sorry for the confusion! We released a major update of the SDK this March which brought in significant improvements due to sensor data.
Do you work for Hypertrack?
Yes.
